Scyphidia

Scyphidia Dujardin, 1841 (ref. ID; 1248, 1555, 2014)

Class Oligohymenophora: Subclass Peritricha: Order Peritrichida: Suborder Sessilina (ref. ID; 2014)
Family Scyphidiidae Kahl, 1935 (ref. ID; 1248)

[ref. ID; 1555]
Type species; Scyphidia rugosa Dujardin, 1841 (ref. ID; 1555)

[ref. ID; 2014]
Solitary. Inverted usually elongated bell-shaped body attached to various animals, both vertebrates and invertebrates, and to submerged objects. There is no stalk and attachment is by a scopula. The macronucleus of various shapes, spherical, elongate or C-shaped but never conical or heart-shaped. The genus is most easily confused with Apiosoma which always has a conical or heart-shaped macronucleus and is limited to growing epizooically on vertebrates.

In 1905, Faure-Fremiet published a classic paper on Scyphidia in which the "sucker-shaped" scyphidian scopula was observed to contact the surface of the host's body only by its free borders. Extending from the vaulted center of the scopula was a brush of immobile cilia, 2-3 um long, which touched the surface of the host by their slightly swollen ends. He suggested that these ends secreted a substance that attached the protozoon to the host tissue. (ref. ID; 3972)
